With the new numba kernel for sparse scaling, we need to figure out how and when the numba code becomes faster than the array code. This might lead to numba completly replaceing the array operations f…

I get this error when calling `kmeans` on a sparse matrix:
```

I need to do operations (+, *, and \ like in DGBTRS in Lapack) on large band-sparse matrices (https://en.wikipedia.org/wiki/Band_matrix), is there a way to do this with breeze without dense matrices?

I am writing code using C++/armadillo, and then writing an interface to R with RcppArmadillo.
In this simple example, I want to multiply two matrices and I can use templates to handle cases where…

It looks as if your code won't convert Sage's sparse matrices. Is it on purpose?

Hi @keewis - I was having a quick look at this package and was wondering how you generate the regridding weights? Is it just with ESMF? And then the [regridder](https://github.com/IAOCEA/xarray-healpy…

In high dimensional statistics, we usually rely on CSC and CSR arrays when matrices are very sparse. It is particularly for speeding up the coordinate descent procedure.
I can implement that in th…
